TTR is a transporter of thyroxine and retinol in the blood and cerebrospinal fluid. When mutated and/or as a result of aging, TTR aggregates into amyloid fibrils that accumulate in organs such as the heart. The segments from the C-terminal region of TTR form in-register steric-zippers with highly-interdigitated, wet interfaces, whereas the Beta-strand B from the N-terminal region of TTR forms an out-of-register assembly, previously associated with oligomeric formation.", "entry": "S-0512", "pdb_id": "6C3T", "global_stoichiometry": "Homo 20-mer - A20 ", "ligand_name": "", "gene_names": "", "inchi_key": "", "ligstr": "", "reference": "Protein Sci. 2018 Jul;27(7):1295-1303.", "inchi": "", "ligand_smiles": "", "ligand_formula": "", "resolution": "1.0", "author": "Saelices, L., Sievers, S.A., Sawaya, M.R., Eisenberg, D.S.", "species": "Homo sapiens", "amyloid_non_amyloid": "Amyloid", "secondary_structure": "AADTWE#CEEECC&AADTWE#CEEECC", "remarks": "AMYLOID FORMING PEPTIDE AADTWE FROM TRANSTHYRETIN WITH ATTR-D38A MUTATION ASSOCIATED WITH A FAMILIAL FORM OF TRANSTHYRETIN AMYLOIDOSIS", "mutation_s_field": "D38A", "length": "6", "keyword": "ALA-ALA-ASP-THR-TRP-GLU", "ligand_mw": "", "type": "Fibril", "r_value_free": "0.124", "alternative_name": "", "peptide_protein_sequence": "chain-ID A: AADTWE; chain-ID B: AADTWE"}
